... well, I live in Canada - my understanding is that the maximum lifetime fine for copyright infringement is about $5,000 when files are shared for personal, non-commercial use...

Which sounds like alot, but if we factor in the extended family and cross-media sharing and the number of separate streaming services we all subscribe to across many many years, then this is a "deal"...

OTOH - I don't want to be the first case/person to help determine what precedent will be set if something actually gets taken to the end-state statutory damages..

On the spectrum of illegality, things can get a lot more extreme than a bit of copyright infringement.

True - I mean, one could try and block based on file-extension/MIME-types, but... nothing stopping a malicious user from renaming a file to an allowed extension, with some sort of malicious/secret payload. (Or... spreading some sort of malware/virus/exploit via media file formats, I have never looked into the possibility of that until just now, apparently it can be a thing - https://cyberpress.org/cybercriminals-exploiting-media-files...)

So yeah - this is probably one of those half-baked ideas that just wouldn't be a good one to actually implement "in-the-wild".
